“…The prolegs are morphologically different among families, adapted to be highly strong and powerful in Saturniidae and Sphingidae 28 and deteriorated in Geometridae and some Noctuidae 13 . Three pairs of thoracic legs, each with a sharp pretarsus terminally, are present in the nal instar larvae of G. menyuanensis (Figs.…”

The grassland caterpillar is a significant pest of alpine meadows in the Qinghai-Tibet Plateau. Its larvae primarily feed on forage grasses, resulting in financial losses. However, little research has been done on the morphological features of larvae of this species thus far. The distribution and habitat of Gynaephora menyuanensis were extensively investigated in this instance through field study. Using an optical and scanning electron microscope(SEM), the external morphology and ultramorphology of the last instar larvaeof G. menyuanensiswere investigated. The findings indicate that this species is primarily found in the northeast of Qinghai Province in alpine meadows at an altitude of 3,000–3,500 m. For the first time, SEM is used to report more comprehensive morphological structuresof G. menyuanensis, including larval head capsule, mouthparts, antenna, sensilla, thoracic legs, prolegs, and setae. The larvae have two distinct color funnel warts (yellow and red) on abdominal segments VI and VII, which sets them apart from other lepidopterous larvae. Additionally, the chaetotaxy of first instar larvae of G. menyuanensis were studied and described in detail, identifying seven clusters(PD, D, SD, L, SV, V, CV) on the larval trunk. This study offers a theoretical basis for phylogenetic analysis, the adaption evolution of G. menyuanensis, and a systematic discussion of the application of morphological features of larvae to classification.

“…C. includens larvae develop through six instars followed by a prepupal stage. The larva presents three pairs of true thoracic legs and three pairs of prolegs (two in abdominal segments five and six and one in the anal segment) (Barrionuevo and San Blas, 2016;Xue and Hua, 2018). This allows them to move with a pronounced looping motion, characteristic of the Plusiinae larvae, due to the lack of abdominal prolegs compared to the normal five present in most of the members of the Noctuidae family (Capinera, 2013) (Fig.…”

In the present thesis, the genetic variability of field-collected isolates of Chrysodeixis includens nucleopolyhedrovirus (ChinNPV) was examined. These results have revealed the great variability present within natural ChinNPV isolates, confirm the differences between two different genetic variants from these isolates and, more important, appear to identify the ChinNPV-K variant as a generator of variability in these isolates. In conclusion, a great variability has been revealed within ChinNPV natural isolates, with a single variant showing a key role in the generation of this diversity in a concentration-dependent manner.
